[04/13] simplify remove_parent()

Commit Message

remove_parent() is a simple wrapper around remove_bb_from_list()
which also set REPEAT_CFG_CLEANUP if the list becomes empty.
But its only user, insert_branch(), doesn't need REPEAT_CFG_CLEANUP
to be set.

So, simplify this wrapper by keeping only the call to remove_bb_from_list().
